After half a century, here is a string of durability, excellent tonality, and good price... I think it is already known to my demanding colleagues...

Tremendous strings. Incredible feel in the hand. You're not afraid to do bends. They really last a long time. I used to buy Ernie Ball strings because they were rated as the best abroad and I needed strings every 15 days.
With the Polyweb, no matter how much my fingers sweat, the strings don't rust. It's been a month and they haven't rusted. I never wipe them after playing and there's a lot of sweat.
So far, they haven't lost their elasticity. It should be noted that I play for about two hours a day.
I haven't tried the Nonoweb and Optiweb yet.
